Amyloid protein AA is the presumptive fragment of an acute phase serum apolipoprotein, apoSAA. Two major murine apoSAA isotypes (apoSAA1 and apoSAA2) have been identified. The NH2-terminal amino acid sequences of purified murine apoSAA1 and apoSAA2 have been examined and compared with that of murine amyloid protein AA. Our results indicate that apoSAA1 and apoSAA2 are separate gene products and that amyloid protein AA has NH2-terminal amino acid sequence identity with only one of these isotypes, namely apoSAA2.
